The device itself is really top class at the price for me to justify the difference in sound quality but not price.
The amplifiers feature was so strong that I already had pain threshold at 5%. So if you have problems with too quiet KH will therefore be determined by the E5 very satisfied.
I get rather better headphones, or to my Sennheiser still a Beyerdynamic instead shelling out for a Itsi-bitsi more Sound Quality 200.
A collected random review I submit anyway because there were no others there.
Pro:
- Improves the sound quality ('d give my Senn 8/10, this DAC / AMP combo 8.7 / 10).
- Many ports (Line-in, -out, 2x amplifier output, large and microUSB slot).
- Can be used as portable battery backup for smartphone.
- Music streaming via Bluetooth from your phone.
- Bass Boost hardly washes out the other frequencies.
- Super design.
Con:
- For the price you get all right great mid-Fi headphones.
- For USB connection to your cell phone, this is ALWAYS loaded.
